My question is not a homework problem. I am having difficulty in understanding the concept oof contact forces.
What I don't understand is that when two bodies A and B are in contact and left on a frictionless surface, they apply normal reactions on each other, then why doesn't that normal reaction force give some acceleration to the blocks and they move away from each other?
The Attempt at a Solution
The only viable solution I can come up with is that the normal reaction is zero, but they why it would be zero I don't know.
